BFKK 1794-OE4 Flex 4-Point Analog Output Module power adapter

Allen Bradley Flex 1794-OE4 Analog Output Module

The Allen Bradley 1794-OE4 is a Flex I/O analog output module designed for programmable logic controller systems. It provides four single-ended, non-isolated output channels for industrial process control. The module requires a nominal external 24 Volts DC power supply for operation. This component suits automation engineers integrating analog control into existing Flex I/O architectures.

Suited for 0-20 mA current loop applications

This module suits installations needing four analog outputs with a 0-20 milliAmps current range per channel. The non-isolated, single-ended design fits systems where common grounding is acceptable and isolation barriers are handled elsewhere. Buyers requiring isolated channels per output or voltage-mode outputs should look at alternative module types. Applications demanding higher channel density or different signal ranges also need a different part.

4 single-ended non-isolated outputs at 0-20 mA

The defining specification is the four single-ended, non-isolated outputs with a maximum current of 0-20 milliAmps each. This output configuration and signal type determine compatibility with your field devices and wiring scheme. Verify that your actuators accept 0-20 mA current loops and that your system design accommodates non-isolated, single-ended wiring. The nominal 24 Volts DC supply requirement must also match your power infrastructure.
